Frequently Asked Questions

Fibreglass resin is a liquid polymer that hardens when mixed with a catalyst, creating a durable, waterproof surface. It’s commonly used in fibreglass roofing systems because of its strength, longevity, and weather resistance.

General-purpose resin is ideal for most roofing applications, offering strong adhesion and durability. Fire-retardant resin, like Pro 25 GRP Fire Retardant Topcoat, provides additional fire protection and complies with building regulations, making it a safer choice for certain installations.

Selecting the right topcoat depends on your needs:

  • Standard Topcoat – Offers UV resistance, a smooth finish, and weather protection.
  • Fire Retardant Topcoat – Provides enhanced fire safety while maintaining durability.
  • Coloured Topcoats – Available in Dark Grey, Mid Grey, and more to match your project’s aesthetics.

Apex Fibreglass Roofing Supplies offers complete roofing kits that include all necessary materials, making the process easier.

Curing times depend on factors like temperature and humidity. Typically:

  • Resin cures in 2–4 hours under normal conditions.
  • Topcoat becomes tack-free within 3–6 hours and fully cures within 24 hours.
